Patent number: 7048831Abstract: The present application discloses a method and apparatus for purging oxygen from a sealed container interior and a purge substance used in such method. The method is exemplified herein in an improved batch process and apparatus for the thermal decomposition of hydrocarbon containing material in a sealed reactor interior. According to the present invention the improved batch process may comprise, 1) loading the hydrocarbon containing material into and sealing the reactor, 2) purging or expelling oxygen from said reactor, and 3) heating said reactor to a predetermined temperature so as to obtain decomposition products, the improvement residing in the purging step including loading the reactor with an oxyphilic solution prior to sealing and heating the interior of the sealed reactor to a predetermined temperature to induce the oxyphilic solution to drive oxygen out of the interior of the container through said gas evacuation component.Type: GrantFiled: June 6, 2002Date of Patent: May 23, 2006Inventors: Richard Bouziane, Gilles Tremblay

Publication number: 20030196883Abstract: A plastic as a material to be treated and an additive such as unsaturated fatty acid oil are mixed, and the mixture is heated in a pyrolysis tank at a temperature of 300° C. to 450° C. by a heating member to thereby thermally decompose the mixture. A gas component produced during the heating process is then removed and a pyrolysate is thus produced.Type: ApplicationFiled: February 28, 2001Publication date: October 23, 2003Applicant: Tokyo Ertec Co., Ltd.Inventors: Yoji Inoue, Satoru Aikawa, Norihiro Inagaki, Shigeru Tasaka

Patent number: 5505822Abstract: A process for treating industrial and/or urban waste includes the steps of drying the waste; effecting thermolysis of the dried waste by direct contact with warm gases, and washing solids resulting from the thermolysis with water to effect dechlorination thereof. Thermolysis is effected by direct contact of the waste with warm gases having a low oxygen content and water for washing the solids is obtained from condensation of vapors generated during drying of the waste A plant for treating industrial and/or urban waste includes a drier for drying the waste, a reactor for thermolyzing the waste, washing the solids from the reactor with water, such as from a condenser, to dechlorinate the solids, and a gas generator to generate warm gases, of which a part of the warm gases are used to heat the drier.Type: GrantFiled: July 9, 1992Date of Patent: April 9, 1996Assignee: Institut Francais du PetroleInventors: Gerard Martin, Robert Gaulard

Patent number: 5478442Abstract: A rotary hearth calciner for treating petroleum cokes with a puffing inhibitor has a horizontal or inwardly sloping hearth floor rotatable around a vertical axis for receiving particles of coke to be calcined and a central opening in the hearth floor for discharging the coke into a soaking pit. A water cooled, refractory covered feed pipe extending downward into the calciner interior has an inlet for connection to a source of petroleum coke puffing inhibitor and an outlet near the edge of the hearth central floor opening for adding the puffing inhibitor to the coke as the coke is discharged from said hearth floor. The feed pipe outlet is approximately at or below the level of the hearth floor to reduce loss of inhibitor in gas flow above the hearth floor. A puffing inhibitor such as sodium carbonate is supplied by a screw feed mechanism to the feed pipe to add the puffing inhibitor at a desired rate for reaction with the coke. The coke is normally maintained in the soaking pit for about 30 minutes at 1200.Type: GrantFiled: February 15, 1995Date of Patent: December 26, 1995Assignee: UCAR Carbon Technology CorporationInventor: Thomas H.
